Ipod read file failed

I use the libxml to parse xml file.
the code is like that :

CCSAXParser parser;

        if (false == parser.init("UTF-8") )
        {
            return false;
        }

        parser.setDelegator(this);

        return parser.parse("game.xml");;

the game.xml file is in the subdir of Resources
When i debug this code under win32 it run good.
but when i debug it under the ios it can not read the content of this file

the game.xml file is in the subdir of Resources
Does it like this Resources/game.xml?

Did the xml was added into xcode?

yes it is at the Resources dir and is add to the xcode.

Does the format of xml is utf-8? I can not think it is the problem.
